Hi,

Install Band-in-a-Box to a new folder, such as C:\bb_test. To do this, you don't need to remove anything first, you won't be installing any RealTracks, and you will simply use whatever Band-in-a-Box 2009 installer you have (if it's the hard drive version, choose the option to only install Band-in-a-Box). This should take a couple minutes to complete.

Next, download and install the build 288 update from:
http://www.pgmusic.com/support_windowsupdates.htm#288

Make sure to install it to the same C:\bb_test folder, and select the option to Launch Band-in-a-Box.

Now you'll be running a fresh install of Band-in-a-Box 2009.5 with the latest update, and you can test to see if you have the same problem. Then we can go from there.
